As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Estoy practicando para ser competente en español. Si publicas en el foro en español, trataré de responder en la misma manera.
The problem is that some graphics cards don't support the GPU-based technique that Vuo uses for 3D object filters such as Trim 3D object (OpenGL transform feedback). One solution would be to provide an alternative (slower) CPU-based implementation. Or possibly this will be fixed when we upgrade Vuo from OpenGL to Metal, we'll see.
Same thing when running in Vuo Editor: If you feed it an image with a transparent background, the background of the output image is pink.
In your composition, the input image is being composited on top of a red background using multiply blend mode. So, transparent areas will show the background (red), and white areas will multiply the background by 1 (1 * red = red). Same with dark green and dark blue. Then it adds the 3 together. red + dark green + dark blue = pink.
To mask out transparent parts of the image, you can use Apply Mask.
